Zipping from Creative Cloud folder

I want to remove some folders on "CC" creative cloud, but keep backup external to adobe ecosystem or propietary anything.

My plan was to use my CC PC/desktop file manager, select a folder from CC synched file system on my pc, and select a folder to use "send to" for zip file output.  

I started to test this today, and was not succesful.  

I get an error "Windows was unable to add one or more empty directories to the compressed (zipped) folder. "

So I'm now wondering what my options are, thinking maybe : 

1) download CC folder on synch adobe cc to my desktop or external drive

2)perform zip on external stored location

3)verify zip/unzip works external source to another external destination

4)delete from cc folder

Any feedback or ideas /concerns from experience would be appreciated.

Thanks, Stephanie
